1. Upload the code into your device. Now your device is sending data to Pybytes.
In this code, we're calling the function
pybytes.send_virtual_pin_value(persistent,
pin, value))
to communicate with Pybytes. This function is part of the Pybytes
library, and it has three arguments:
persistent
,
pin
and
value
.
persistent
denotes information that is infrequently accessed and not likely to
be modified;
pin
represents which virtual pin is receiving data;
value
is the value being attributed to that particular pin.
Step 2: Add a signal from your device
Go to Pybytes.
